Keynote lectures of the summer school were given by Prof. Flávio de Andrade Silva from PUC Rio de Janeiro, Brazil, who introduced recent developments in textile-reinforced concrete with a focus on sustainable applications using natural fibers; Prof. Avraham N. Dancygier from Technion – Israel Institute of Technology, who presented innovative engineering solutions for enhancing the resistance of reinforced concrete protective structures under extreme loads. Prof. Andrea Nobili from the University of Modena and Reggio Emilia, Italy, discussed a robust cohesive fracture model addressing crack propagation during fiber pullout in concrete. Additionally, Dr.-Ing. Frank Liebold, associated to the program as graduate from the first cohort of the GRK 2250, offered an insightful talk on image-based techniques for crack monitoring in civil engineering material tests.
